Filling housing for looms having multiple filling yarn spools

BPOGi SH/RE ATTORMSVJ United States Patent 3,236,265 FILLING HOUSING FOR LOOMS HAVING MULTIPLE FILLHNG YARN SPOOLS Grover John Brookshire, Black Mountain, N.C., assignor to Beacon Manufacturing Company, a corporation of Delaware Filed Dec. 9, 1963, Ser. No. 328,819 2 Claims. (Cl. 139-122) This invention relates to housings for filling yarn spools 0n textile looms and especially to housings for the filling yarn spools on textile looms of the type which utilize a plurality of spools of filling yarn of difierent types during a Weaving operation.

A type of textile loom which utilizes a plurality of spools of filling yarns is the Sulzer loom illustrated in the Pfarrwaller patent, US. Patent No. 2,817,367, issued December 24, 1957. In this type of loom a supply of filling yarn is alternately pulled ofi a plurality of spools.

A problem arose in this type of loom in that when a supply of filling yarn was pulled from each of the spools, it was pulled with such a force as to pull off more yarn than was actually required at that time. This left the excessive amount of yarn pulled 01f each spool dangling down below the spool an appreciable length. Due to the inherent twist in the yarn, it would twist and kink in its downward position. When the cycle of the loom again came around to use filling yarn from these spools, it would jerk or pull the yarn again and the excessive amount of yarn which was hanging down in a kinked form would cause the yarn to break due to the kinks and twist in the yarn.

This type of loom normally utilizes the plurality of spools of filling yarn on one side of the loom disposed in pairs with one spool of each pair disposed over the other spool of each pair. The trailing end of yarn from one spool of the pair is tied to the leading end of the yarn from the other spool so that when the yarn from one spool is exhausted the other spool will automatically supply .the necessary filling yarn. The pairs of spools are normally provided with a housing which encloses each pair, but no separation is provided between the spools of each pair. Therefore, the above mentioned problem became quite acute with the yarn pulled from the upper spool of each pair.

It is an object of this invention to provide an improved housing for filling yarn spools on the above mentioned type of loom which will prevent the yarn from hanging or dangling down with excessive kink or twist therein which causes breakage of the filling yarn during normal weaving operations.

This object is accomplished by providing a platform between the spools of each pair, therefore providing a resting place for the excessive yarn being pulled oil the top spool of each pair, to prevent same from dangling down and kinking.

Further features of this invention will be understood from a consideration of the following more detailed description taken in conjunction with the accompanying drawings in which:

FIG. 1 is a side elevation view in cross section of the novel filling housing of this invention, and

FIG. 2 is a top view taken along the lines 11 of FIG. 1 and illustrates the novel platform used in the housing of this invention.

Referring now to FIGURES 1 and 2, a pair of filling yarn spools 1 and 2 are shown disposed over and under each other in a vertical plane on shaft 3. The spool 1 has filling yarn 4 thereon and the spool 2 has filling yarn 5 thereon. The trailing end of yarn 4 is tied to the leading end of yarn 5 so that when spool 1 is exhausted, spool 2 will furnish the filling yarn.

During normal weaving operation of the loom, yarn 4 is pulled from spool 1 with a substantial force to supply sufiicient yarn for one pick of the weaving operation. This pulling operation occurs very rapidly and due to the force at which the yarn is pulled from the spool, an excessive amount of yarn is pulled from the spool 1. Without the novel housing of this invention, this excessive amount of yarn could dangle down for an appreciable length and become kinked and twisted due to the inherent twist in the yarn. This kinking and twisting and dangling down causes substantial breaking in this yarn when a supply of yarn is again pulled from the spool.

The filling housing of this invention comprises outer housing 6. The outer housing 6, as may be seen in FIGS. 1 and 2, encloses the pair of spools 1 and 2 on three sides. Cooperating with the housing 6 is a platform 7 comprised of two plates 8 and 9. The plates 8 and 9 overlap each other and are spaced slightly from each other so that when yarn 4 is exhausted, the trailing end of yarn 4 will be able to pull the leading end of yarn 5 between the plates to supply filling yarn to the loom through the aperture in outer housing 6.

During operation of the loom, the platform 7 will catch or support the filling yarn 4 as it is pulled off of spool 1 to prevent the yarn from dangling down and excessively kinking or twisting. When the yarn 4 is again pulled from spool 1, it will not break as the yarn is supported on platform 7. When the spool 1 is exhausted the trailing end of yarn 4 will pull the leading end of yarn 5 from spool 2 through the space between plates 8 and 9 so that the spool 2 will now supply the necessary filling yarn. In like manner, the outer housing 6 will now serve as a platform for the yarn 5 when it is pulled from the spool 2, and therefore, the yarn 5 does not hang down an appreciable amount to cause excessive twisting and kinking when it is pulled from the spool 2,

This invention has therefore provided a novel housing arrangement for the pair of filling yarn spools to prevent breakage in the yarn as it is pulled from the spools during normal weaving operations.

This invention has been described in detail above for purposes of illustration only and is not intended to be limited by this description or otherwise, except as defined in the appended claims.

What is claimed is:

1. A means for preventing breakage of filling yarns in a loom having at least two superimposed supply packages of filling yarn in which the trailing end of one package is connected to the leading end of the other package for providing an unexhausted supply of filling yarn to the loom between the two packages; said means comprising a platform disposed between the packages of filling yarn and adapted to catch and support excess filling yarn pulled from the upper package during a prior feeding operation of the filling yarn to the loom to prevent the yarn from hanging down an appreciable amount from the upper package to become twisted and k-i-nked and broken during subsequent feeding operations of the filling yarn to the loom, said platform comprising a pair of plates spaced from each other slightly in a vertical direction and slightly overlapping each other in a horizontal direction to define an opening therebetween to allow the passage of the filling yarn there-between from one side of said platform to the other side of said platform when the filling yarns from one package is exhausted and the trailing end of the one package pulls the leading end of the other package to supply filling yarn to the loom.

2. A means for preventing breakage of filling yarns in a loom having at least two superimposed supply packages of filling yarn in which the trailing end of one package is connected to the leading end of the other package for providing an unexhausted supply of filling yarn to the loom between the two packages; said means comprising a platform disposed between the packages of filling yarn and adapted to catch and support excess filling yarn pulled from the upper package during a prior feeding operation of the filling yarn to the loom to prevent the yarn from hanging down an appreciable amount from the upper package to become twisted and kinked and broken during subsequent feeding operations of the filling yarn to the loom, and an outer housing disposed at least partially around the filling yarn packages and underlying the lower package and adapted to catch and support excess filling yarn pulled from the lower package during a prior feeding operation of the filling yarn to the loom to prevent the yarn from hanging down an appreciable amount from the lower package to become twisted and kinked and broken during subsequent feeding operations of the fill-ing yarns to the loom, said platform comprising a pair of plates spaced from each other slightly in a vertical direction and slightly overlapping each other in a horizontal direction to define an opening therebetWee-n to all-0W the passage of the filling yarn therebetween from one side of said platform to the other side of said platform when the filling yarn from one package is exhausted and the trailing end of the one package pulls the leading end of the other package to supply filling yarn to the loom.
